Use the tabletop TBL-75 in a stereo or multi-room audio setup to keep volume adjustments at your fingertips. You can simply connect it between your amplifier and a single pair of speakers, or run up to sixteen pairs thanks to built-in impedance-matching technology. Connect your favorite pair of headphones to the front-panel jack for private listening.

Features

Overview: The Russound TBL-75 is a free-standing, 126-watt tabletop
volume control with a headphone jack and built-in impedance-matching options. It
connects between the speaker outputs of an amplifier or receiver and a pair of
speakers and can just provide volume control for a pair of headphones. The
TBL-75 adjusts the volume of the speakers connected to it by adjusting the
signal from the amplifier to the speakers. Connecting headphones disconnects the
speakers in the room for private listening.

Precision Autoformers: The Russound tabletop volume controls is made
with precision autoformers for high-fidelity sound, excellent frequency
response, no heat buildup, and maximum power transfer from the amplifier to the
speakers.

UltraMatch Impedance Switching: An impedance switch on the TBL-75
allows installers to easily match the load of multiple speaker pairs to the
amplifier impedance without the need for a speaker selector or other
impedance-matching equipment. When using the TBL-75 in installations with
more than one pair of speakers or additional volume controls, the TBL-75 has a
rear panel impedance selector switch to be set at 1x, 2x, 4x, or 8x. The 1x
setting allows the TBL-75 to be used as a standard volume control. The 2x, 4x
and 8x settings allows it to used a an UltrMatch impedance matching volume
control. The UltraMatch volume control matches the minimum output impedance of
the amplifier or receiver, in addition to adjusting the volume. It eliminates
the need for a speaker selector or additional impedance matching equipment. The
TBL-75 can be used with 4 to 8-ohm speakers. It will allow impedance matching
for up to 16 speaker pairs per system.

Connections: The Russound TBL-75 features connections for a pair of
speakers and set of headphones.

Note: You should not use solid-core, aluminum or Romex type
wire with this volume control.

Headphone Output: The TBL-75 is equipped with a front-panel 1/4"
headphone output designed to connect an optional set of headphones.
Connecting your headphones disconnects the speakers connected to this unit
for private listening and the unit's volume knob controls the headphone
audio levels.

Mounting: The TBL-75 offers a freestanding design so it can be located
on a desk, counter, or tabletop.

Does what it is supposed to do

There really isn't much to say. The Russound TBL-75 sits quietly doing its job of reducing sound levels. For people who have stereo amplifiers with provision for A and B speakers but no volume control for the rear speakers and who want to use those speakers as front and rear speakers in the same room, the Russound is a handy piece of equipment, particularly if your listening position is closer to the rear speakers. The sound level can be adjusted so there is a harmonious whole without being made unpleasantly aware of the rear speakers.
